 (synopsis "Raspberry Pi GPIO, SPI, I2C, and ePaper display drivers for OCaml")
 (description "
An OCaml library for Raspberry Pi hardware interfaces using ctypes:

- GPIO: Character device API (/dev/gpiochipN) with support for input/output and pull-up/down resistors
- SPI: Full SPI communication support
- I2C: I2C bus communication
- Device Drivers:
  * MAX7219: LED matrix displays (daisy-chain support)
  * DS3231: Real-time clock with temperature sensor
  * AT24C32: 4KB EEPROM
  * Waveshare ePaper: E-ink display support (2.13inch V4)

All drivers use the modern GPIO character device API and are compatible with Raspberry Pi.")
